Again, spoilers:

Another gripe for me, is the whole situation about the missing family. Firstly -- Nora was killed, then frozen. Since Cyro freezes a body's age, and physiology, surely if you were to reopen it, she would have died relatively speaking 2 minutes ago. Surely the institute has the means to either revive her, or create a synth copy who belives she is Nora? Also, why couldn't Father clone himself and give the baby clone to the vault dweller?

There's a happy ending for all this. Just surprised Bethesda didn't take it.

Kinda wished their was more choice when it came to the end, like being about to change the Brotherhoods mind of the institute, or change the institudes mind of synths being people, or changing the railroads mind on synths being dangerous. It was too much of a linar ending, and I disagreed with every faction xD But then again they did limit the dialog system to 4 options so I guess we should have expected it.

I've just finished the game. (If you don't want game-ruining spoilers, don't read on!)
To me, the ending was really, just... meh. I knew that the faction I chose would eventually get rid of the other two, so the ending held me no suprise. After I spoke to Father at the end, the game finished and I was like... now what?

Try playing it on survival. You get one every 5 minutes ;_;
